Rectangle (Standard Sheet)


Specify your corner radii in mm.
We will assume the orientation of your sheet matches the diagram below. To leave a corner square enter a value of 0.

Please note, there is not a standard radius. If you are unsure, we would recommend that the radius is equal to the sheet thickness. I.e. 3mm thick material would have a 3mm radius corner.

Rounded edges box



NB Drawing is not to scale.


This feature gives you the ability to have your sheet pre-drilled with four holes (one in each corner) for easy mounting.

For panels with a longest side of over 1000mm we recommend two extra holes for wall mounting to reduce flex. These will be placed half way along the longest side at no extra charge. If you require these extra holes please specify in the special instructions at the checkout.

Drill location square
Specify your location for these holes by entering a value in mm for the distance between the edge of the sheet and the center of the hole as shown in the diagram by x or y.

Polycarbonate greenhouse panels make the ideal replacement for old or damaged glass panels. Not only is polycarbonate sheet (also known as ‘Lexan’) up to 200 times stronger than traditional glass but it is also half the weight - making it the perfect material for greenhouse panels. 

Cut Plastic Sheeting offer replacement polycarbonate greenhouse panels in a wide variety of thicknesses cut to your exact size requirements.

Polycarbonate sheeting is one of the best plastic materials available for glass replacement applications:

  • High light transparency - up to 90%
  • Unbeatable impact resistance
  • Flexible
  • Lightweight
  • Available with polished edges
  • Easy to handle and work with
  • Excellent weather resistance
  • Very low moisture absorption
  • Trade names include ‘Lexan’, 'Makrolon' and 'Macrolux
  • Supplied with protective film on both sides

We offer polycarbonate sheet in 3mm, 4mm, 5mm, 6mm, 8mm and 10mm but for greenhouse and shed applications 4mm is more than adequate.

High impact polycarbonate greenhouse panels will make light work of repelling common garden hazards such as footballs, falling apples, frisbees, animals and children.
